lis3706 - Clearing a form

Since we haven't been taught this, I figured I'd throw what I found up here.
This is the Default.aspx.cs file (ie: the code)

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
 
public partial class Default2 : System.Web.UI.Page
{
     protected void ButtonClear_Click(object sender, EventArgs e)
     {
          Box1.Text = "";
     }
}

Below is the default.aspx file.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>
 
<!DOCTYPE html PUBLIC "-W3CDTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="Box1" runat="server"></asp:TextBox>
<asp:Button ID="reset" runat="server" Text="Button" onClick="ButtonClear_Click"/>
</div>
</form>
</body>
</html>

Clearing Form Fields without initiating Validation Controls

Most validation controls will execute whenever any button on the form is clicked. This is problematic for a Clear button as you don't expect the data in the form fields to be valid (why else would the user be clearing it).

To override this behavior, simply add the following attribute to your button control:

<asp:Button ID="reset" runat="server" Text="Button" causesValidation="false" onClick="ButtonClear_Click"/>
